Flash App npviewer.bin Slowing Firefox and my Fedora 13 System Down Allot! Using 50 to 100% of CPU Resources!

On my Fedora 13 - 32 Bit System. I have been having trouble with Flash Videos using up 50% to 100% of my CPU Resources!!! This has been going on for several months now and I could not find any answers or a fix for this problem. Today, I found nspluginwrapper installed in my Fedora 13 - 32 Bit System... I used System Monitor Version 4.4.5 (KDE 4.4.5) to see what was going on with my System. After finding the npviewer.bin process using 50% of my CPU Resources. Then I learned that this is a Flash Plugin Process. The Problem is, that Flash and npviewer.bin uses 50% to 100% of my CPU's Resources. I did a search in Add-Remove Apps for npviewer and the only App that came up was, nspluginwrapper. The Web Site link is no longer any good in the Repo's link. But here is the info they give...

"nspluginwrapper makes it possible to use Netscape 4 compatible plugins compiled for i386 into Mozilla for another architecture, e.g. x86_64.
This package consists in: * npviewer: the plugin viewer * npwrapper.so: the browser-side plugin * nspluginplayer: stand-alone NPAPI plugin player * mozilla-plugin-config: a tool to manage plugins installation and update"

I'm going to uninstall this App and see if it fixes my Problems. This is Beyond aggravating and has almost crippled my beloved Firefox:( Google Chrome, handles Flash a little better, but still is vulnerable to this problem. On the plus side. I have learned to appreciate Chrome a little more lately;) It would be great if it just had all of the features that Firefox has;) Here's some more info that I found, which helped to lead me to this conclusion...

Update: This did help allot!:)

Ok, This is Great!!!:) Now the plugin-containe Process handles the Flash Videos.

    It's related to flash-player in 64bit I think, the package nspluginwrapper supplies it
    Flash player is 32 bit arch, this enables it's use in a 64 bit environment.

    Hm, though running a 32bit system, I also have this package:

    Code:
    kalle@hoppers:~> locate npview /usr/lib/nspluginwrapper/i386/linux/npviewer /usr/lib/nspluginwrapper/i386/linux/npviewer.bin /usr/lib/nspluginwrapper/noarch/npviewer
    I remember npviewer.bin being pretty annoying when having watched Flash-content: after finishing Flash it would still appear in my process-list untill manually killed. This got solved by some update I suppose, at least Flash is behaving nicely over here since a while now.

    You can delete it on 32 bit. I have. And flash is fine.
    I bug reported this yonks ago, back in 11.1 the same behaviour. It seemed to get installed by default. Yet I remember helping folk who, with _64, had managed to install flash-player and yet not have nspluginwrapper! Strange..

It is a Problem for Fedora 13 - 64Bit Systems too.
This is what i'm getting on my freshly installed Fedora 13 x64 Gnome system eith latest firefox and updated 100% . Flash player version 10.1.53.64 .When i use google-chrome-unstable v6, the problem rarely occurs  After some 4, 5 errors the system freezes

A quick search for: WARNING: unhandled variable 18, returns the following bug: https://bugs.launchpad.net/ubuntu/+source/nspluginwrapper/+bug/592492  It suggests that setting "dom.ipc.plugins.enabled=true" in about:config.   With this set right clicking on the flash player correctly shows the context menu and does not freeze Firefox.  This appears to be an effective workaround but not a fix since a firefox config setting should not freeze Firefox/NSPlugin.    This is what I see for the page http://www.redhat.com/promo/summit/2010/highlights/ from terminal with "dom.ipc.plugins.enabled=true":

Question Firefox crash: npviewer.bin is not responding.

Firefox crashes frequently when surfing on certain pages.

Is there something to be done about this?

Well, now I am bit more confused

I have mozilla-vlc plugin installed. What I thinkl I found out is that it might cause the problem or then solve it. I don't have nspluginwrapper installed unless it has installed with some other software.

But, one thing that I found common to my pc crashing is that everytime there are multiple npviewers open when I kill firefox after hangup.

What is the actual reason for hangups?

Sometimes not a single one of those flash contents on a page is shown.
Then on the same site on another subpage multiple flashes work without any problem.

It does not really matter, since they usually are just adds.

But it does matter when browser crashes because of it.

Can anyone tell why the hangup occurs in the first place?
My guess is that web designers are trying too hard to make fancy technical pages and have totally forgotten for what reason webpages are made for.

Most probably yes.
I have installed so many different linux distros to many pc's recently that I am not quite sure.
Usually I have downloaded latest version everytime I install linux.

How is this possible. I'd understand if fedora were a commercial product and the driving force would be a quick earnings. Maybe two versions per year is bit too much to handle.

Thumbs up Installing Swiftfox helped.

It seems that browser/flashplayer does not crash anymore and shows flash content correctly.

But some other issue came up. Some links and filenames do not work.

Ok, This is Great!!!:) I after uninstalling the nspluginwrapper. Now the plugin-containe Process handles the Flash Videos. At least it does on the Page that gave me all of my headaches today. It's at, http://reeltruths.com/cool-it/ if you want to use this one as a test for yours. Now my Firefox is only using 5% CPU and 129MG of Memory and the plugin-containe Process handling the Flash Video is only using 15% to (at most on startup of the video) 30% CPU and 39MB of Memory. That's more like it!!! I have now idea if the nspluginwrapper App was installed along with another App (Browser or Player perhaps) or if I installed it my self, just because it sounded good in the description. I do that allot... I find interesting Apps and install them to see if I like the. Then later, I have no memory of it at all:o I know, I know... But I can't help my self;)
